TURF Examples

The following examples show the command that
produces the TURF output, the TURF report and
the REACH.RESULTS file. The TURF commands can
be entered manually or generated from the pull
down menus. Examples using TURF from the menus can
be found in the manual "P-STAT:An Introductory Guide
for Windows Users".

The following is a small input file which is
used in the first few examples. The case id
will never be used in the analyses. Variable www
contains weights and will only be used when the
CASE.WEIGHT option is desired.

A TURF analysis using case weights

------------TURF analysis for file ddd completed-------------
| OPTIONS: case.weights (in variable www) |
| |
| 5 items were used in the analysis. |
| |
| 16 cases were read and used; the sum |
| of the weights for these cases was 20. |
| |
| 16 cases had at least one positive response. |
| The sum of the weights for these cases was 20, |
| making that the maximum possible reach. |
| |
| SIZE 3 evaluated 10 combinations: |
| 17 was the best REACH, found in 1 combination. |
| 17 was the FREQ value in that combination. |
| 19 was the best FREQ in any size 3 combination. |
| |
| The FREQ score for a combination is the count of |
| non-zero responses in the case for that combination, |
| times the caseweight, summed over the reached cases. |
| |
| REACH.RESULTS file workcw has the 10 |
| combinations with the highest reach scores. |
| The items are ordered by their REACH contribution. |
| Cumulative reach is shown. |
| |
| Time: less than 0.1 second. |
